ammo on remand To all whom it may concern:

Be it known that I, Auaxammn Lnvm'r, a citizen of the United States, and a resident of the city of New York, boro h of Manhattan, in the county and State 0 New York, have invented a new and Improved Bufling or Polishing Wheel of which the following is a full, clear, and exact description.

The invention relates to bufling or polishi wheels made of cotton, wool, leather or o t fiermaterial, and its obept is to provide a new and im roved bu or polishing wheel arm to prevent t e loss of the material of which the wheel is made and to permit of using the wheel until the material is worn away, practically down to the hub or center piece. Another object is to provide a bufling or polishing wheel which 18 exceedin 1y strong and durable and which can Ee'cheaply and quickly manufactured with a minimum amount of material.

With these and other objects in view the invention consists of certaln novel features of construction as hereinafter shown and described and thenspecifically pointed out in the claims. A practical embodiment of the invention is represented in the accompanying drawings forming a art of this .spec1fication,. in which similar 0 cate corresponding parts in all the views.

and gathered or forming the of a sin 1e stri of doubled u materia and t e apparatus In the manufacture of bufiing or polishing wheels of woven fabric strips as heretofore been customary to superimpose such strips and to fasten the same together by stitches a distance from the margmal edge of a strip. Now as the wheel wears down tothe row of stitches the remalmng marginal portion of the strip becomes detached and flies off the rotating wheel by t e centrifugal force and hence such material is not utilized for bufling or polishing purposes and is lost. In in inventlon presently to be described in (Ltail the strip of material is doubled up 'widthwise and gathered along the doubled up or median edge, and this stri is wound onthe hu b or center of the w eel to rm1t of uslng the strip up to the athered edge, that is, to the center or hu of the wheel, and very little material is lost.

In 1ts simplest form, a strip 10 of cloth or other suitable vmaterial is doubled up widthwlse to provide a median line or edge 11 and members 12 and 13, the outer edges of which form the peripheral face of the wheel. The gathered edge 11 is 'wound around a core or disk 14. By' the arrangement described a unit is formed and any number of such units may be placed together, one alongside the other asshown in Flg. 2, for making a bufiing or polishing wheel of a desired width. The op faces of the body are covered b dis 15 connected with each other by rivets, bolts osite" or other suitable fastening means 16, not" string '20 tied around the outermost layer,

as plainly indicated in Figs. 6, 7, and 8. Inpractice, theunit is formed 'on an apparatus such as shown and described in my appliof the Umted States, No. 233,757, filed b me on MaylO, 1918. In the a paratus s own in Fig. 8 the core 14 is he (1 between two disks 21and 22 with an axle v23 extending centrall throu h the core and held in the disks 2 22. e material is wound ar und. the d sks 1 around the disks 21 and 22.

preferably out has fashion from a piece of of the mem-' 20 and 21 once are number of times and with the middle of the material at the ve formed between the disks. The string or cord 20 is now placed around thematerial opposite the groove anddrawn tight to draw the material into the groove and with'the edge 11 against the peripheral face of the core 14 thereby gathering the material and doubling up the 12 and 13, as plainly indicated in Fig. 8. The core 14 is preferably built up of a number of superimposed disks like material according to the thickness: of the unit body formedbythe members 12 and 13 and which lattercorrespondeach to the number of windings given. the material The strip material so that the outer edges bers 12 and 13 do not ravel thus insuring the proper: use of the bufling or polishing wheel without any waste of material.

In order to give more fullnes to the bulling or polishing wheel, the main strip 10 is provided with two intermediatestrips of material 25 each doubled up widthwise to provide a median line or edge 26 and members 27 and 28. The strips 25 are fastened alongtheir median lines 26 by stitches 29 to the members carrying strip 10 12 and 13 of the main or and at a point a distance from the median line 11 of the main or carrying strip 10. To

is secured an outer doubled up strip 30 of material similar to that of which the main stri 10 and the intermediate strips 25 are ma e, and this outer strip has a median line 31 and two members 32 and 33. Each strip 30 is fastened along its median line 31*by stitches 34 to the member 27 of the corresponding intermediate strip 25 a distance intermediate the outer and, inner edges of'the said member 27, as will be readily understood by reference to Figs. 1, 3, 4, 5 and 6. The outer edges of the several members 12, 13, 27, 28, 32 and 33 are disposed in the same plane and formthe peripheraledge of the butting or. polishing; wheel. It will be noticed that themain orcarr ing strip 10 is wider than the strips 25 .an the latter are wider than the strips 30, and the strips 25 and 30 are arranged between the members 12 and .13 of the outer or carrying strip" 10. By the. arrangement described a body is formed; of a series of strips providinglsu rlayers, each strip beingv ou led I up widthwise along the median line of the strip thus providin each strip with two members of practice ly equal widt The main strip 10 is further provided 40 doubled up widthwise and fastene alon its median line 41-by stitches 42 to the oubled up edge 11 of the main or carrying stri 10, as plainly shown in Figs. 1, 3,4, 5 an 6. a This doubled up ate strips 25.

'It will be noticed that when the buffing or lishing wheel is in use and its periphera edge is gradually worn down until the stitches 34 are reached then the outer strips 30 have been com letely used without any loss of material. hen

It will further be noticed that by doubling up the strips and fastening the same together along the median linean exceedingly large number of layers of material are provided in the body 10 of the wheel.

It is understood that in each unit the strip is wound around the hub or center at least once but in practice the strip is wound around a number of times to form superimposed layers doubled up widthwise and gathered at the doubled up edge, as above illustrated in the drawings.

It is further understood that I do not limit myself to any particular material of which the strips are made, as cotton, wool, or other material may be used.

It is further understood that I do not limit myselfto the number of doubled up auxiliary stri s of fabricmaterial shown and describe as; the same may be increased or entirely eliminated without-deviating from the spiritrof my invention. Having thus described my invention, I
